A Bunsen burner, named after Robert Bunsen, is a kind of ambient air gas burner used as laboratory equipment; it produces a single open gas flame, ...
Robert Wilhelm Eberhard Bunsen (German:; 30 March 1811 [a] – 16 August 1899) was a German chemist.He investigated emission spectra of heated elements, and discovered caesium (in 1860) and rubidium (in 1861) with the physicist Gustav Kirchhoff. [11]
Robert Bunsen invented the now-famous Bunsen burner in 1855, which was useful in flame tests due to its non-luminous flame that did not disrupt the colors emitted by the test materials. [ 4 ] [ 1 ] The Bunsen burner , combined with a prism (filtering the color interference of contaminants ), led to the creation of the spectroscope , capable of ...
The fishtail burner was similar to the flat burner, but it produced a brighter flame and conducted less heat. The last burner that was experimented with was the Welsbach burner. Around this time the Bunsen burner was in use along with some forms of electricity. The Welsbach was based on the idea of the Bunsen burner, still using gas.
In a Bunsen flame, a steady flow rate is provided which matches the flame speed so as to stabilize the flame. If the flow rate is below the flame speed, the flame will move upstream until the fuel is consumed or until it encounters a flame holder. If the flow rate is equal to the flame speed, we would expect a stationary flat flame front normal ...
The first gas heater made use of the same principles as the Bunsen burner. Beginning in 1881, the burner's flame was used to heat a structure made of asbestos, a design patented by Sigismund Leoni, a British engineer. Later, fire clay replaced the asbestos because it is easier to mold.
It is well established that conventional "blue flame" or bunsen gas burners produce oxides of nitrogen at levels of 30-50 nanograms per joule [5] [6] and are as such not considered to have potential for NO x reduction. Surface combustion burners or radiant tile burners in comparison produce nitrogen oxides' levels 60-70% less. [6]
Leaving the loop in the flame of a Bunsen burner or alcohol burner until it glows red ensures that any infectious agent is inactivated or killed. This is commonly used for small metal or glass objects, but not for large objects (see Incineration below). However, during the initial heating, infectious material may be sprayed from the wire ...
